All subdomains suddently redirect to parent site?

Well - semms to be messed up. The question is why?

You have some ispcp-backups of the apache config. You could need them to add the vhosts in the apache-ispcp.conf.
Or try this: set the status-field in the ispcp-DB of all domains to "change" and let the request manager run.
